Question

A very large force acting for a very short time is known as

• A. Impulsive force
• B. Momentum
• C. Inertia
• D. Cohesive force

Answer 1

Answer:

A. Impulsive force

An impulsive force is defined as a very large force acting for an extremely short duration of time. This interaction results in a significant change in momentum of an object, and the overall effect is quantified by the impulse (Impulse = Force × time interval).

• Momentum (B) is a measure of mass in motion (mass × velocity).

• Inertia (C) is the tendency of an object to resist changes in its state of motion.

• Cohesive force (D) is the attractive force between molecules of the same substance.
